Choosing the Best Circular Saw

Cordless Circular Saws

Circular saws are versatile tools that are geared towards DIYers and carpenters alike, and are widely used along with other types of saws including jigsaws. This type of saw can be used to perform bevel cuts, cross cuts, and ripping materials such as hardwood, plywood and softwood with the integrated blade.
Just like most power tools, circular saws are available in a choice of corded and cordless models, where the former are powered by an electrical outlet, and latter with rechargeable lithium ion batteries with no wires to deal with. Buying a cordless circular saw can be a complex affair if you don’t know what to look for, but the following tips should guide you on the right track, and help you buy the right tool for the job.

Cordless vs. corded models

Choosing between the two models will depend mostly on how you plan on using the saw. Cordless circular saws are great when working in tight spaces and/or those where extension cords are challenging to use. Corded circular saws require a suitable extension cord, and are ideal for cutting jobs such as steel, masonry and continuous woodworking.

Features to look out for

    • Power – The power of a cordless tool is measured in watts, where the higher the number, the more cutting power.
    • Blade size – Blades for circular saws are available across a spectrum of sizes, most commonly 7-1/4 inches. Saws that offer blade capacities of 6″ and higher are ideal for most cutting tasks, whereas those with a smaller blade are lighter and easier to control. Furthermore, blades are available in steel and carbide-tipped versions, where the former are an economical choice, and the latter are more durable.
    • Bevel capacity – Circular saws with this feature allow you to make angled cuts, so look for tools with positive stops and tool-free adjustment for improved accuracy and efficiency to adjust for common angles.
    • Electric brake – This stops the blade from spinning when you release the trigger, which both enhances safety and gets the tool ready quickly for the next cut.
    • Easy change blade system – Some offer tool-free blade changes or the ability to change them in a single step, resulting in reduced downtime especially if you change blades frequently.
    • Dust blower – An integrated blower cleans the dust to improve visibility. Some circular saws can also be connected with a shop vacuum to collect sawdust as you use the tool.
    • Cast metal housing – This shields the motor from wear and tear and extends its service life.
    • Blade guard – a protective layer that covers the blade when not in use, and retracts when the tool is in use.
    • Ergonomics – Tools with non-slip soft handles are easier to control and hold especially when working for longer periods.
    • Safety features – A lock off button prevents the cordless circular saw from starting up before you intend it, and a soft start switch sets the blade moving at a lower speed when you first fire up the tool, improving control over the cut.
